Mni Wiconi Pipeline consists of water treatment plant, several water storage reservoirs (both ground and elevated), several pump stations, river crossings (both buried and bridge structure) and approximately 400 miles of generally 16 inch diameter welded steel water transmission pipeline with some minor PVC branch transmission pipelines.  

Aaron Swan and Associates (AS&A) provided surveying, construction field engineering and materials testing services on Phases I, II, III, IV, V, VI, VII, VIII and IX.   

Aaron Swan and Associates is currently providing the surveying, construction field engineering and materials testing services on Phase VIII and IX of the Mni Wiconi Pipeline Project.  The surveying consists of establishing control points using conventional total station and GPS.  The project utilizes a coordinate system which traverses from the Ft. Pierre water treatment plant to the project’s terminus on the Pine Ridge Indian Reservation; this coordinate system is a modified state plain system.  Once the project’s controls have been set, ASA is required to survey the proposed alignment and profile a ROW strip.  This information is then provided to the “Design Engineers” for their approval.  After approval, AS&A will make any necessary adjustments to the alignment and, provide the ROW and construction staking using the pipe manufacturer’s lay-sheets and design grade lines. 

Also, AS&A is providing the field engineering that consists of preparing the SDDENR Surface Water Discharge Permit, Erosion Control Plans, Traffic Control Plans and Construction Materials Testing.
